Carbon dating definition in chemistry
What is Carbon Dating? The age of archaeological specimens can be calculated by looking at the amount of carbon - 14 in a sample. The method is a form of radio dating called carbon dating. Radio dating can also be used to date rocks. How is Carbon - 14 formed? The isotope carbon - 14 is created at a constant rate in the upper atmosphere by cosmic rays acting on nitrogen.
